INSTRUCTIONS
• PLEASE study these instructions carefully before installing your new camshaft. If you have any questions or problems, do not hesitate to call our
Technical Hotline at: 1-800-416-8628.
• CAMSHAFT: Edelbrock Performer-Plus camshafts are ground specifically for use with the corresponding Performer manifold #2151 on engines
operating from idle to 5500 rpm. The Performer Olds 455 manifold #2151 and Performer-Plus camshaft #2152 are designed to work as a team
to give you better driveability and performance. They are dyno-matched and street-proven. For best results, use the Edelbrock manifold/camshaft
package with the carburetor and headers we recommend.
NOTE: Maximum performance is achieved when the Edelbrock Performer Olds 455 Power Package components are used with the following
equipment:
•
Performer Olds 455 manifold/camshaft/timing set/valve springs
•
Original Equipment Quadrajet carburetor (w/electric choke) or Edelbrock carburetor #1407 or #1411
•
1-3/4" headers
•
aftermarket/re-curved distributors
•
any combination of the above
• IMPORTANT: This instruction sheet provides general installation guidelines which can affect your warranty. Read it carefully. It is not our intent to
cover each detail of installation here; a step-by-step procedure manual would be far too lengthy. We want to caution you that installing a
camshaft is a complicated procedure that requires a good general knowledge of automotive engines. If you are not confident that you can complete the camshaft installation successfully, we suggest you consider having it installed by an experienced mechanic.
CAUTION: Improper installation will result in LOW MILEAGE, POOR PERFORMANCE, COSTLY REINSTALLATION, and ENGINE DAMAGE.
TO AVOID THESE PROBLEMS YOU MUST DO THE FOLLOWING:
Carefully study and understand all instructions.
Examine the camshaft for possible shipping damage (if damaged contact your dealer immediately).

VALVE SPRINGS
CAUTION: WARNINGS ABOUT YOUR WARRANTY
In order for this Performer-Plus cam and lifter kit to be covered
under ANY WARRANTY you MUST use the correct original equipment valve springs or equivalent. Failure to install new Edelbrock
valve springs or OE equivalent with your new Performer-Plus cam
could cause the cam lobes to wear excessively and could cause
additional engine damage.
This camshaft is designed to function with stock valve springs. Do
not use dual valve springs with this camshaft.
When using stock valve springs, check and set spring height to factory specifications for correct year and model
NOTE: Due to various settings throughout the years, we advise
checking Motors, Chilton, or Oldsmobile service manuals or correct
spring height for your vehicle.

LIFTERS
New lifters must be used with a new camshaft. Use only the lifters
supplied with this kit.
Check to be sure that all lifters fit freely in the lifter bores.
CAUTION: Some engines use a .921" diameter lifter. If you have
this size lifter, you must purchase TRW VL-59, Speed-Pro #HT-957,
or contact Mondello Performance Products, phone # (805) 2378808.
INSTALLATION INSTRUCTIONS
Coat cam lobes and bottoms of each lifter with MoS2 lube (supplied) to prevent cam lobe and lifter wear from occurring during initial start-up. Do not "pump up" lifters before installation!
Install new camshaft with new sprockets, timing chain and lifters.
CAUTION: Use Edelbrock Performer-Plus True Rolling Timing Chain
and Gear Set #7813. Do not use late model timing chain & gear
sets that are designed in a retarded position and are not recommended for this camshaft installation. Edelbrock Timing Sets feature three keyways for specific timing selection. Use locking compound material on the bolt threads holding timing gear to cam.
Torque to factory recommendations specified in motor repair manual.
Install camshaft with timing marks lined up as recommended by
factory specifications. See Figure 2.
When using Performer-Plus Timing Chain and Gear Set #7813 with
Edelbrock cam and lifter kits, straight up timing alignment is
achieved. If any other timing gear set is used, it is necessary to
check cam position for correct timing alignment. This requires
indexing the camshaft with a degree wheel to verify timing alignment. O.E.M. or non-Edelbrock timing gear sets are not recommended for use with Edelbrock camshafts.
•
INSTALLING PUSHRODS AND ROCKER ARMS
After the cam is installed and timed correctly (see Figure 2), it will
be necessary to check each pushrod for correct lifter pre-load.
Before installation, be sure to coat friction surfaces of pushrods,
rocker arms and pivots with a suitable lubricant such as motor oil
or assembly lube.
•
1.
VALVE ADJUSTMENT
Turn the engine over until the No. 1 cylinder is at Top Dead Center
(TDC) on the compression stroke (both lifters will be at the bottom
of their travel in the lifter bores). Install both intake and exhaust
pushrods, rocker arms, rocker arm pivot, and rocker arm bolts.
Carefully tighten bolts while feeling pushrods for vertical clearance.
As soon as all vertical clearance is gone from pushrods, count
number of turns until bolts bottom out. There should be 1/2 turn of
lifter pre-load. If vertical clearance exists after bolts bottom out,
longer-than-stock pushrods are required. If excessive lifter pre-load
exists, use shims under rocker arm pivots to achieve 1/2 turn preload.
The above procedure assures correct lifter pre-load. Repeat this
procedure for each of the other seven cylinders by
rotating the engine 90° and following the firing order
(1-8-4-3-6-5-7-2).
Re-install front cover, fuel pump, water pump, and oil pan using
new gaskets.
Install intake manifold using new intake gasket set and torque
manifold bolts to 25 ft./lbs.
Install crankshaft dampener and torque to factory specs.

INSTALLING DISTRIBUTOR AND TIMING ENGINE
NOTE: Before installing your distributor, check the gear drive on the
distributor and oil pump for any signs of wear. If worn, be sure to
replace with new or you may wear out your camshaft prematurely.
Edelbrock camshafts are designed to use OEM-type gears only.
Turn the engine over in the direction of rotation until the No. 1
intake valve closes and continue until the pointer on the front cover
is approximately 5 degrees BTDC.
Re-install the distributor with the rotor pointing towards No. 1 terminal in the cap, and with the vacuum advance canister in its original position.
Lightly tighten the hold-down clamp so that the distributor can still
be turned to determine final setting using a timing light with the
engine running.
Replace valve covers, carburetor linkage and remaining vacuum
and electrical connections.
Re-install air conditioner, if so equipped.
Refill radiator with coolant and re-connect battery.
Double check all connections, fuel lines, etc. before starting engine.

CAMSHAFT/LIFTER RUN-IN
1.
CAUTION: Change the engine oil and filter before start-up and again
after initial break-in. Do not allow the engine to run under 2000
rpm for the first 1/2 hour. Vary engine speed between 2000 and
2500 rpm. Slow idle speeds may result in severe cam and lifter
wear.
Start the engine and bring to break-in rpm.

IGNITION TIMING
Ignition timing for this package may vary with each application. A
good starting figure would be between 10 degrees to 14 degrees
initial timing at idle with vacuum advance disconnected. Total
advance should not exceed 32 degrees to 34 degrees with initial
and centrifugal weights combined and should be at full advance at
3000-3500 rpm. After timing is adjusted, re-connect the vacuum
advance line. NOTE: The best combination for any particular vehicle
or application must be determined by trial and error using the
above information as a guideline.
•
HEADERS
For best performance, headers are recommended. For this application, they should be 1-5/8" or 1-3/4" diameter, approximately 31"
long and terminating into a 3" collector. The remainder of the
exhaust system should consist of dual exhaust and tail pipes, at
least 2" diameter with low back-pressure mufflers.
•
WARNING
In order for this Performer-Plus cam and lifter kit to be covered
under ANY WARRANTY you MUST use the correct Edelbrock Sure
Seat Valve Springs or original equipment equivalent. The end flap
or label from your Sure Seat Valve Spring box must be sent in with
your camshaft warranty card.
Failure to install new Edelbrock Sure Seat Valve Springs or
Performer-Plus cam and lifter kit could cause the cam lobes to
wear excessively and could cause additional engine damage. IF
YOU HAVE ANY QUESTIONS ABOUT THIS APPLICATION, PLEASE
CONTACT OUR TECHNICAL DEPARTMENT IMMEDIATELY.
IMPORTANT INSTRUCTIONS
AFFECTING YOUR WARRANTY
CAM LOBE WEAR- Cam lobe wear is almost non-existent unless
mismatched parts are used or installation of the cam and lifters is
done improperly. Most cam damage is caused by the timing gear
coming loose due to improper torque on bolt. Bolts holding gear to
camshaft should be torqued carefully and a locking compound
applied to threads of bolts.
CAM GEARS AND CAMSHAFT END PLAY- If cam gear becomes
loose, the cam will slide back in the block, causing the lifters to hit
the lobes next to them and also the cam bearing journals. If the
engine is run after this happens, the bottom of the lifters and the
sides of the lobes will become chipped.
When installing a camshaft, it is always important to check for
proper operating clearances, especially when high performance
components are used. Things to look for that can cause failure and
damaged parts are as follows:
Improper valve-to-piston clearance (this should be no less than
0.080”).
Rocker arm stud slot clearance (both ends; valve closed and open).
Proper spring settings (see dimensions with spring instruction
sheet; correct dimensions mean maximum performance and longer
engine life).
SPECIAL INSTRUCTIONS
With the Edelbrock manifold and camshaft package plus a header
installation, a carburetor jet change may be required for best performance. Due to the varied applications of year and model of vehicles, no one combination could suffice for all installations. The following procedure is only a guideline and in many cases, the manufacturing specifications for recommended carburetors or timing
may be best.
